PLOW ATTACHMENT.

Application filed January 14, 1909.

To all whom fit may concern:

Be it known that I, JAMES E. BURTON, a citizen of the United States,residing at TWhitewater, in the county of lalworth and Sta-te ofldlisconsin, have invented certain new and useful Improvements in PlowAttachments, of which the following is a speciication.

The object of this invention is a cheap, light and simple constructionin drag attachments for plows, which by its arrangement of parts may beeasily secured to a walking plow and properly adjusted at the rear ofthe mold-board irrespective of the particular type of plow to which itis attached, or the length of the beam thereof, the invention alsomaking provision for the lateral adjustment of the drag attachment ifdesired;

lVith this and other objects in view, the invention consists in certainconstructions, arrangements and combinations of parts that I shallhereinafter fully describe and claim.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawings, in which,

Figure 1 is a perspective view of a walking plow equipped with myimproved drag attachment. Fig. 2 is a horizontal sectional view throughthe rear end of the attachment, the harrow frame being shown in top planview. Fig. 3 is a transverse sectional view of the attachment looking atthe front of the harrow frame. Fig. l is a detail view, partly insection, illustrating the connection of the draft rod with the means forholding it at the front end of the plow. Fig. 5 is a detail view, partlyin section, of one form of device for holding the drag attachment atdifferent elevations. Figs. 6 and 7 are detail views illustratingdifferent modified forms, and Fig. 8 illustrates in top plan viewanother modified form in which the drag device is a harrow of therevolving disk type.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, A designates the clevis, B the beam, C thehandles and D the mold-board of a walking plow which I have hereselected for the purpose of illustration only, and which may be of anydesired type of construction.

1 designates the draft rodfor the harrow or other drag attachment. Thisrod is de- Specicaton of Letters Patent.

signed to extend longitudinally to one side of the plow and is intendedto have its front end mounted in a socket 2 that is formed on the upperend of a vertically disposed pin or post 3, the rod projecting throughthe socket and being held therein rigidly as against both a longitudinaland rotary movement by set screws 4 or similar clamping devices. Thesupporting post 3 is mounted within a vertically disposed tube 5 andextends therethrough, being held detachably therein by means of a cotterpin 6, or the like. The tube 5 is formed on one end of a transverselyextending pin 7 which may be secured by any desired clamps to the plowbeam, but which is preferably inserted through the clevis and heldtherein by a cotter, or the like.

The rear end of the draft rod 1 is extended outwardly, as indicated at8, and thence forwardly as at 9, to form a U-shaped frame upon which theharrow E or drag attachment is intended to be supported. In oneembodiment of, the invention, the harrow E comprises front and rearmetal bars 10 which are joined together at one end by a preferablylongitudinally elongated spring loop 11, which may be either securedthereto or formed integral therewith. The bars 10 are formed on theiropposing faces with shoulders 12 forming clips between which the harrowteeth 13 may be clamped when the two bars are drawn together and held bymeans of a series of clamping bolts 14. In order to adjustably securet-he harrow upon the frame formeel by the angular construction of thedraft rod 1 at the rear end thereof, I may employ eye-bolts 15 that areslipped upon the draft rod and that pass upwardly between the front andrear bars 10 of the harrow, the nuts of the bolts being tightened tohold the harrow securely in place after the two bars 1() have beensecurely clamped together, the said nuts bearing upon the upper faces ofthe bars.

F designates a bracket which is designed to be secured to the handleportion of the plow and which is intended to support the rear end of therod 1 and the harrow or other drag attachment mounted thereon. Thisbracketvis formed with a substantially U-shaped portion embodyingouterand inner standards designated 16 and 17 respectively, the innerstandard 17 being formed with or secured to an attaching bar 1S which isdesigned to extend across the handles C and may be secured to thisbracket 22 by slipping two of the bars 10 through the bracket before thebars are clamped together and turningl the harrow frame around until theloop 11 is mounted in the bracket. It is to be noted that thisconstruction permits the harrow frame to have a limited forward andbacl-:ward movement in the bracket 22. The sleeve 21 carries a casing23. An angle lever 211': is journaled at its elbow in the casing 23, andone end of said lever is connected to a latch 25 which is adapted toextend through an opening in the sleeve and into engagement with any oneof a vertically extending series of sockets or keepers 26 formed in theouter standard 16. The other arm of the lever 24 is pivotally connectedto a handle rod 27 which extends up through the relatively stationaryhandle 28 that projects outwardly from the upper end of the sleeve 21,the upper end ofthe handle rod carrying a hand grip 29. An expansionspring 30 encircles the rod 27 between the hand grip 29 and handle 28and exerts a tension upon the rod in a direction to move the latch 25into locking` engagement with the standard 16. By gripping the handle 28and hand grip 29, the operator may, by pressing the two together,release the latch 25 from the standard 16 and raise and lower the sleeve21, thereby effecting the raising and lowering of the harrow, which bythis means may be adjusted to work at different depths if required. 1tis obvious that by this means also, the harrow may be raised to aninoperative position out of the ground and held in such position byengagement of the latch 25 with the standard 16, when the plow isturning' corners, or whenever for any other purpose this inoperativeposition of the harrow is desired.

F or a modication of my invention, reference is to be had to F ig. 6,wherein the harrow frame designated E is substantially like the harrowframe before described, except as will be now noted. The front and rearbars 102l of the harrow frame E are provided at their connection withthe spring loop 11a, with depending lugs 81 which meet to formpractically one lug when the bars are clamped together and which aredesigned to engage a notch 16b in the supporting Standard 16a when theharrow is raised to an inoperative position and moved slightly inwardly,the harrow being thereby supported out of the ground. 1n order to raisethe harrow, as shown in this view, as a modification of the adjusting'means before described, a handle 32 is provided which is formed withoppositely extending angle ends, the lower one of which is drilled sothat it may be slipped over one of the eyebolts 15a that secure theharrow to the draft rod 1a, the nut of said bolt clamping the handledown upon the bars of the harrow.

1t is to be understood that my invention is not limited to a harrowframe constructed of metal, as described. For instance, as illustratedin Fig. 7, E2 designates a harrow which is constructed of wood with theteeth 13a driven therein, the harrow beingsupported upon the rod 1b andsecured thereon by eye-bolts 15b, and being provided at one end with ametal strip 11b which constitutes the loop which receives the standard16. 32a designates the handle in this instance, secured to the harrowlike the handle 32, and by which the harrow may be raised to slide theloop 11b upwardly on the standard 16C, and by pulling slightly inwardlyon the harrow will cause the lower edge of the loop 11b to enter thenotch in the upper end of the standard, whereby to support the harrow inan inoperative position. 1t is also to be understood that my inventionis not limited to a harrow as the drag devices, nor to a particular formof harrow as the toothed harrow hereinbefore set forth. For example, asillustrated in Fig. 8 the harrow may be of the revolving disk form, t-hegang of disks 33 being mounted upon the outwardly extending rear end ofthe draft rod 1c and revolving thereon as an axle.

1n the practical operation of my improved drag attachment, the draft rodis secured to the front end of the beam or to the clevis by the meanshereinbefore described and is adjusted in its supporting post accordingto the particular length of the beam holding the desired position of theharrow in the rear of the mold-board, and the harrow is let down uponthe standard 16 into opera-tive relation to the ground, being supportedby the said rod which will thus serve as a drag rod to drag the harrowalong as the plow is advanced. 1n turning corners, or for any otherpurpose, it is desired that the harrow shall be held in an elevated orinoperative. position, the devices hereinbefore described, are employedto lift the harrow outI of the ground and support it either by theengagement of the latch 25 with one of the higher notches 26 of thestandard 16, or by resting the lugs 31 or lower edge of the strap 11b onthe notched upper end of the standard 16a or 16C.

1t is evident that the lateral adjustment of the attaching bar 18provides not only for the fastening of the bracket F to plows withhandle portions of different width, but also enables the operator toposition the liarrow or other' drag devices different distances from theplow beam, in the rear of the moldboard. It is to be noted that after ithas once been adjusted to the plow, my improved device may be attachedor detached without the necessity of a wrench or any implement of thiskind.

Having thus described the invention, what is claimed as new is l. Thecombination with a plow, a draft rod connected at its front end theretoand formed with an outwardly and upwardly extending rear endconstituting a supporting frame, a drag device adjustably mounted uponsaid frame and provided at its inner end with a loop, and means carriedby the handle portion of the plow for engaging said loop.

2. The combination with a plow, of a draft rod connected thereto nearits front end and extending rearwardly along the plow to one sidethereof, the draft rod being formed with an angular rear endconstituting` a frame, a drag device supported on said frame andprovided at its inner end with a loop and a bracket secured to the plowand arranged for engagement with said loop.

3. The combination with a plow, of a draft rod connected thereto andextending rearwardly along the plow to one side thereof, a drag devicecarried by the rear end of said rod and provided at its inner end with aloop, a bracket secured to the plow and embodying an upwardly extendingstandard and a vertically movable connection between said standard andloop.

4f. The combination with a plow, of a draft rod connected thereto nearits front end and extending rearwardly along the plow at one sidethereof, a drag device carried by the rear end of said rod, a bracketadjustably connected to the handle portion of the plow and embodying anupwardly extending standard, a vertically movable connection betweensaid standard and the inner end of the drag device, and means forholding the drag device in an elevated position on the standard.

The combination with a plow provided with a clevis, of a pin extendingtransversely through said clevis, a vertically disposed tube secured toone end of said pin, a post mounted in said tube and provided at itsupper end with a socket, a draft rod adjustably mounted in said socketand designed to extend rearwardly along one side of the plow, a dragdevice carried by the rear end of said rod, and means for connectingsaid drag device with the plow.

ln testimony whereof I aflix my signature in presence of two witnesses.
